Application filed June 5 This invention relates to new and useful improvements in educational appliances.

The object of the invention is to provlde a device for training the memory, increasing the accuracy of the vision, and exercising the mental faculties thereby making the user more alert as well as quicker of perception.

Another object oi the invention is to produce an appliance so arranged as to display a plurality of cards or similar objectsinrows together with means for quickly inverting the cards simultaneously whereby their faces are hidden, and to again manipulate the cards in the opposite direction to display their faces.

A further object oi the invention is to provide means for holding a plurality of cards or the like in rows or pairs so that the cards may be quickly and readily inserted in the desired place and likewise removed.

A still further object of the invention is the simplifying of the construction shown in my Patent No. 1,509,371 dated Sept. 23, 1924, by eliminating the transparent holders, the sand glass, etc.

A construction designed to carry out the invention will be hereinafter described together with other "features of the invention.

The invention will be more readily undcrstood from a reading of the following specification and by reference. to the accompanying drawings. in which an example or" the invention'is shown, and wherein Fig. 1 is a plan view 01": an appliance constructed in accordance with my invention,

Fig. 2 is a side elevation of the same,

Fig. 3 is a longitudinal sectional view taken on the line 3-3 of Fig. 1,

Fig. 1 is an enlarged sectional view taken on the line 4t--4 of Fig. 1, showing its inverted position in dotted lines,

Fig. 5 is a plan view of the same, and

Fig. 6 is a partial plan view of the device showing the holders in their inverted position.

In the drawings the numeral 10 designates a rectangular frame preferably made of angle iron in which a plurality of transverse bars 11, are suitably pivoted. Each bar which is substantially square in crosssection, has trunnions 12 at eachend and are. fulcruined in the upright portion of the li'lfi.

1924. Serial No. 718,749.

allow ample clearance for cards to be inserted without overlapping at their outer edges. Each holder comprises two outer fingers 14 and an intermediate finger 15 which is of less length. The fingers have curved upper portions allowing the insertion of the cards to be done readily and quickly. The intermediate finger is laterally oiiset or bent out of the plane of the outer fingers, which provides sur'licient space for the cards A to be inserted, thereby forming a clip for the same as the fingers are preterably made of spring metal.

Mounted on one end of each bar 11 is a short arm 16. These arms are pivoted to the side of an operating bar 1?, which is disposed at one side of the frame. The bar has a knob 18 suitably mounted to its central portion.

It will be seen that by grasping the knob and swinging the bar upwardly and longitudinally the card holders will be inverted. Moving the bar in one direction inverts the holders and moving the same in the. opposite or return direction restores the holders to their original position face down.

In using the appliance a number of or dinary playing cards or other cards which may be combined in pairs or groups are employed. The cards A are dealt singly and inserted in the holders side by side as to lie face down as shown in Fig. 1. Aft-er the desired number of holders are filled, the device is ready to use.

The knob of the operating bar is grasped and moved upwardly and outwardly, whereby the card holders are inverted and the cards A are presented face upward. The student is instructed to memorize the location of as many cards as he can pair, or group into other combinations. are then inverted to their original position, face down by swinging the bar 17 upwardly and toward the operator. The student is then instructed to remove the cards in pairs or other combinations which he has mentally formed previously. The results determine the students alertness and perception.

When the holders are inverted to display the faces of the cards a certain length of time is allowed to memorize the position of the various cards. The time may be lengthened or shortened according to the age or intellect of the. user. The appliance may be used as a game in nterestin 5 vi The cards Various changes in the size and shape of the 'difierent parts, as Well as modifications and alterations may be made Within the scope of the appended claim.

What I claim, is:

An educational appliance comprising a frame, a plurality of card holders pivoted therein, a plurality of strips secured to said holders and having groups of separated fingers projecting laterally therefrom for 10 supporting cards beyond the holder in order that opposite faces thereof may be visible upon reversal, and means for oscillating the holders for less than a revolution to invert the cards thereon.

In testimony whereof I afiix my signature.
